The potential of foreign body aspiration or ingestion is a worldwide health problem in dentistry. The general dental practitioners should be extremely attentive in handling of minor instruments during any intervention related to the oral cavity, especially in the supine or semi-recumbent position of the patient. Aspiration cases are usually more critical and less common than ingestion. We report a case of iatrogenic aspiration of an endodontic broach, which gets disclosed during the recording of past dental history of the patient. The patient was asymptomatic during that time. A quick posterior-anterior chest radiograph was taken which revealed the presence of broach in the lower lobe of the left lung. The patient was immediately referred to the pulmonary medicine department where the fiberoptic bronchoscope retrieval was planned, and the same was carried out successfully under local anesthesia. Although such accidents have rare occurrence, the associated risks and morbidity are too high to be overlooked, especially from the viewpoint of special care, resources, and the associated financial cost required for their management. Moreover, practitioners are also liable for malpractice litigation given the fact that such cases are avoidable. This article also discusses relevant review literature, risk factors, symptoms, and management of such iatrogenic accidents along with drawing attention to the significance of preventive measures and their role in avoiding meritorious legal and ethical issues.

Background: Frenectomy is complete excision of the frenum attachment to the underlying bone. Conventional frenectomy with blade has been widely used; however, laser-assisted frenectomy is the most recent alternative. Aim: The present study aims to compare two methods of frenectomy for the pain experienced, intraoperative bleeding, healing outcome, and need for analgesics. Materials and Methods: Twenty patients with high labial frenum attachment requiring frenectomy were included in this study. Patients were randomly divided into Group A: scalpel group and Group B: neodymium-doped yttrium aluminum garnet (Nd:YAG) laser group. Visual Analog pain score, intraoperative bleeding, number of analgesics used, and healing outcome 3 months postoperatively were recorded. Results: Group B patients experienced less pain (P = 0.016), less bleeding (P = 0.016), and required fewer number of analgesics (P = 0.008). Healing outcome at 3 months showed no significant difference between the two groups (P = 0.095). Conclusion: Based on the results of this study, it can be concluded that Nd:YAG laser is an efficient and a more comfortable alternative to scalpel for frenectomy.

For its utilization as a biocompatible regenerative material not only in dental but also in medical fields. The following systematic review has gathered all the currently available in vitro, animal, and clinical studies utilizing PubMed electronic database from January 2006 to August 2016 highlighting PRF for soft and hard tissue regeneration and/or wound healing. Although results are encouraging but require further validation from clinical studies to justify the potential role of PRF in periodontal regeneration so that this relatively inexpensive autologous biomaterial can be utilized at a wider scale....

Aim of this trial was to evaluate the combined clinical and radiographic success rate of endodontic treatment using passive ultrasonic irrigation (PUI) and laser activated irrigation (LAI) as compared to conventional syringe irrigation. Permanent incisors and single rooted premolars were assessed for eligibility and 69 patients were randomly divided into three treatment groups (n=23) by allocation concealment method and irrigation was performed in accordance with the allocated group. Teeth were evaluated clinically and radiographically with CBCT after 6 months and 12 months of the treatment. A significant difference was observed in the radiographic healing rates among three groups (χ2=12.29, p=0.05). On comparing the final outcome among the three groups (n=19), it was found that 2 (10.5%) cases of group I(Conventional Syringe irrigation), 7 (36.8%) cases of group II (Passive ultrasonic irrigation) and 8 (42.1%) cases of group III(Laser activated irrigation) were healed while under healing category 13 (68.4%) cases of group I, 12 (63.2%) cases of group II and 11 (57.9%) of group III were observed whereas 4 (21.1%) cases were categorised as diseased in group I only. LAI and PUI can increase the predictability of the endodontic treatment success in cases of chronic apical periodontitis.

Aim: The aim of the study is to evaluate and compare the in-vitro remineralization efficacy of remineralizing agents, i.e., fluoride-free toothpaste, fluoride toothpaste, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), CPP-amorphous calcium fluoride phosphate (CPP ACFP), and silver diamine fluoride (SDF) paste on dentine over time. Methodology: Seventy-five extracted human permanent molars were selected. The buccal section of these samples was shaped into a slab. Artificial caries was induced by dipping the samples into the demineralizing solution (pH 4.5) for 21 days. They were then divided into five groups (n = 15). Each experimental group underwent one of the following treatments: Group 1 – Fluoride-free toothpaste (negative control), Group 2 – Fluoride toothpaste (positive control), Group 3 – CPP-ACP, Group 4 – CPP-Amorphous Calcium fluoride Phosphate and Group 5 – SDF. Postremineralizing treatment, Scanning electron microscope, Energy dispersive X-ray and Quantitative light induced fluorescence imaging were carried out to analyze the remineralizing efficacy. The data obtained was then subjected to statistical analysis using ANOVA and Paired t-tests. Results: It was seen that SDF showed highest remineralization efficacy followed by CPP-amorphous calcium fluoride phosphate, CPP-ACP, fluoride toothpaste and fluoride-free toothpaste. The difference in mean value among the groups was statistically significant (P < 0.001). Conclusion: SDF showed the highest remineralizing potential in scanning electron microscopy and energy dispersive X-ray, followed by CPP-ACFP, CPP-ACP, Fluoride toothpaste, and Fluoride-free toothpaste. Quantitative light fluorescence analysis showed more fluorescence changes in the CPP-ACFP followed by CPP-ACP, Fluoride toothpaste, and Fluoride-free toothpaste.
